' SPECIFICATION forming part of Letters Patent No. 772,581, dated October 18, 1904.

Application filed April 26, 1904:.. Serial No. 2Q4,962. (N0 model.)

To all whom it may concern:

Be it known that we, RoMULUs RAwsoN and EDWARD LODGE, subjects of King Edward VII of Great Britain, residing at Hudders field, in the county of York, England, have invented certain new .and useful Improvements in Dyeing or Treating with Liquids Yarn in the Cop or Cheese, of which the following is a specification.

This invention has reference to the dyeing, scouring, bleaching, or similar treatment with liquids of textile fibers made up in the form of cops or cheeses. v r V The object of this invention is to dye, scour, or bleach yarn in the cop or cheese instead of in the hank and to subject the whole yarn. mass from center to circumference of the cop' built up one above the other, a portion only of said frames being shown. Fig. 3 is atransverse section of the cop-frame shown in Figs. 1 and 2, showing a slight structuralmodification. Fig. A is-a plan view of aportion of our improved frame for holding cheeses. Fig. 5 is a transverse'section taken on line 1 2 of Fig. 4. Figs. 6 and 6 are plan and cross-section,

respectively, of a fragment of frame, showing a modification hereinafter referred to. Fig. 7 is an elevation showing a series of frames built up in a tank or vessel with pump and connections for continuously circulating the liquor through the frames. Fig. 8 is a longitudinalsection of one end' of a cop-frame such as illustrated at Fig. 1. Figs. 9 and 10 are -plan view and longitudinal section, respectively, showing a cop-frame cast or made in one piece. Fig. 11 is a cross-section illustrating a modified construction of the frames.

Referring to the drawings, and first to Figs. 1 to 5, letter 60 represents a frame of square, rectangular, or other suitable shape. Integral with said frame or secured thereto are a series of parallel bars or rods a, spaced at equal distances apart to leave open spaces between each bar, the sides of the bars being preferably curved to the segment of a circle to form semicircular pockets of substantially the diameter and shape of a cop, as shown at Figs. 1 and 2, or of a cheese, as shown at Figs. i and 5, or said bars may be made triangular in cross-section, as shown at Fig. 8,

the object being, whatever shape of recess may be formed by the section of bars employed, to admit of cops or cheeses b fitting closely in the said recesses to prevent any,

clearpassage being left between the cops or cheeses and the bars for liquid to get through.

Fitting in the spaces between each bar in the frame, at suitable distances apart longitudinally of said bars are a series of loose blocks 0. those for the cop-frame shaped or dished out at one end to receive the nose of a cop and at the opposite end to receive the base of a cop, so that the bases of the cops in, say,the first row of cops fit in the correspondingly-shaped ends of the blocks between same and the second row, while the noses of the latter row of cops fit in the opposite ends of said blocks. The

blocks for the cheese-frames are provided with open bearings to receive the tubes on which the cheeses are built. The blocks in each series or row are secured by screws or like means to a loose plate or cross-bar cl on the under side of the frame, so that the whole of the blocks in each row can be bodily moved or adjusted longitudinallyof the bars a to accommodate cops or cheese of different lengths. In lieu of the blocks in each row being secured to a crossbar, as described, they may each be provided with a T-base or foot 0, adapted to be passed through an enlarged opening d at one end of each recess and slid longitudinally of the bars to any position, as illustrated'at Figs. 6 and 6, each individual block thus being adjustable separately. The frames 1/ are made of suitable depth, so that when placed one upon the other, as illustrated at Figs. 2 and 5, the cops or cheeses in one frame will be clear of the frame placed above it. Around the upper edges or faces of each frame is secured any suitable packing or jointing strip to make an air and liquid tight joint between the frames when built up one on the top of the other.

A single frame filled with cops or cheeses may be dealt with at one time, or in dyeing, bleaching, or scouring large quantities of yarn a series of frames would most commonly be employed and be built up in a vat or vessel e, as shown at Fig. 7 or on a fiat bed, as the frames themselves form a vessel, the said bed or bottom of the vat or vessel having one end of a pipe f connected thereto which communicates at its'opposite end with a pump 9, to which is connected one end of a second pipe it, whose opposite open end terminates over the frame or pile of frames. In using a single frame or a series of frames the sides of the frame or of the top frame may be extended to form a well of suitable depth above the cops or cheeses to hold the top water or said well may be conveniently formed by a plain frame placed on the cop or cheese filled frame or upper frame of the series, as indicated at 76 in Fig. 7, the said frame and the cop or cheese filled frame or frames being secured or held firmly down upon the bed or bottom of the vessel and upon each other by screws or bolts or by end plates or wedges m,

wedged tightly between a cross head or bar Z, secured by uprights to the flat bed or bottom of the vessel and the upper edges of the top frame, as shown at Fig. 7. The vessel or the well above the built-up series of frames is first charged with a supply of dye liquor (or scouring or bleaching or other liquid as the case may be) and the pump then set in motion. The action of the pump draws the liquid down through the frame or frames to the outlet-pipe f; but as the openings in the frame or frames are closed up by the cops or cheeses it necessarily follows that to reach said outlet the liquor or liquid must pass through the bodies of the cops or cheeses, which are thus thoroughly saturated with the liquor from core to circumference and yarn dyed throughout. The liquor or liquid drawn through the frames by the pump 9 is forced through pipe it, which delivers it to the top of the frames again and maintains a continuous circulation which can be kept up as long as desired to get the best results, and when discontinued the said pipe ]a, which mayconveniently be a flexible pipe, is arranged to deliver the dye or other liquid into a storage vessel ready for reuse at the next operation. The heating of the liquors or liquids may be effected by coils, jacketed frames, or direct steam in any of the well-known ways. If the frames are jacketed or made hollow, the parallel bars a may also be made hollow to admit of steam or hot or cold air being circulated therethrough for heating or drying or cooling purposes, and in some cases the hollow bars could be perforated at the sides and cold or hot air or steam blown through the perforations direct upon the cops or cheeses laid between the bars.

In dealing largely with cops of a given length and size the frame could be cast or made with a series of recesses of the same size and shape as the cops, as at Figs. 9 and 10. so that the said caps would just fit into same. A similar frame might also be employed for cheeses.

In Fig. 11 we show a slight modification in the construction of our improved frame in which the upper and under sides are made to receive cops or cheeses, the object of such construction being that when two or more frames are built up one above the other the cops in the recesses on the upper sides of the lower frames will enter and fit in the recesses on the under sides of the upper frames, and thus be held firmly on each side. In using frames of this or similar construction the liquor or liquid could first be drawn down through the frames, and after circulating in that direction for some time could subsequently be forced in the reverse direction or upward through the frames.

Having fully described our invention, what we claim, and desire to secure by Letters Patent, is-
